New faces: DT Ndamukong Suh, LB Deone Bucannon, OLB Shaquil Barrett, LB Devin White, WR Breshad Perriman, QB Blaine Gabbert, P Bradley Pinion, CB Sean Bunting, CB Jamel Dean, K Matt Gay

They’re gone: DT Gerald McCoy, LB Kwon Alexander, WR DeSean Jackson, WR Adam Humphries, CB Brent Grimes, QB Ryan Fitzpatrick, DE Vinny Curry

2019 snapshot: A disappointing team in an extremely difficult division, the Bucs might have made their biggest upgrades this offseason in the coaching staff.

Replacing Dirk Koetter is Bruce Arians, fresh off a one-year retirement. He brought many of the key pieces from his successful staff in Arizona, including D-coordinator Todd Bowles, offensive minds Harold Goodwin and Byron Leftwich, and special-teams coordinator Keith Armstrong.

Elsewhere, GM Jason Licht’s approach raised more question marks. LT Donovan Smith’s extension (three years, $41.3 million) was reasonable in an out-of-control O-line market, as was letting Alexander depart for San Francisco at a ridiculous price (four years, $54 million).

But while White (fifth overall pick) should thrive in place of Alexander, he represented an exorbitant investment at a position of marginal value, while the Bucs spent fewer resources on the edge. Barrett was a bargain, but there are few other dangerous rushers after Jason Pierre-Paul’s neck injury. Releasing McCoy and signing Suh while saving $3.75 million seems like a win, but Suh isn’t necessarily the better player, and he’s certainly not the leader McCoy was.

Licht also invested heavily at both kicker (Gay) — a few years after his disastrous trade-up for Roberto Aguayo — and punter (Pinion), positions that rarely justify any sort of significant price tag or draft capital.

Get to know… CB Carlton Davis.

With second- and third-round picks spent on cornerbacks in the 2019 draft, Davis was on the spot entering training camp. But he often looked like the best competitor on the outside and is playing up to his own potential as a 2018 second-round pick.

Worth the investment?

–The Bucs went 5-11 last season and shouldn’t be any worse, so going over their 6.5 over/under win total is certainly achievable, as long as Jameis Winston clicks with Arians.

–Speaking of Winston, his MVP odds (+10000) are tied for 37th-best in the NFL, behind several wideouts and even defensive players. Given Arians’ history — he helped Carson Palmer finish as an MVP runner-up in 2015 — that could be one of the best longshots on the board.

Bottom line: Bringing in Arians gives Winston his best shot at success, but it’s hard to get on board with the rest of what Licht did. The Bucs have a lot of work to do in a tough NFC South.
